One in the booty and one in the mouth, high five up top and that's what it's about. it's the Eiffle Tower.
The Arch De Triumph is a slight variation, same set up only instead of the high five you shake hands.

The Eiffel Tower can only be done in a 3-some with a friends or maybe even ur best homie while the skank is on al fours one guy sticks it into her ass or pussy whichever one you prefer and the other gets head while their hands collide in an all mighty high five

Yo last night me and jarred picked up this skank at a party and we Eiffle Tower that bitch so hard nut came out of her nose
